The Algonquin Radio Observatory (ARO) is a radio telescope research facility located in the Algonquin Provincial Park in Ontario, Canada. The site's primary instrument is a major 46 m (150 ft) parabolic-dish radio antenna. This instrument is historically famous for taking part in the first successful very long baseline interferometry experiment in the 1960s. The site also formerly ran a solar-observing array of thirty-two 10 ft (3 m) dishes, and a single 1.8 m solar flux monitor observing at 10.7 cm wavelength. The site is currently used to provide high accuracy geodetic location information to the present day for applications such as real time GPS signal correction.
